Technology Integration
The Technology Integration (TechInt) group is charged with delivering new technologies into the Leadership Computing Facility (OLCF) by identifying gaps in the system software and hardware stack and develop, harden, and deploy solutions. Their technology scope includes file and storage systems, system architecture, non-volatile memory, data management, high-performance networking, intelligent facility operations, and data analytics. TechInt staff work to design and procure the OLCF systems (Titan, Summit, Frontier, Spider, HPSS, and data analysis clusters), develop the infrastructure that supports these systems, and keep OLCF ahead of the technology curve. They research and evaluate emerging technologies in the aforementioned areas and provide the systems programming to seamlessly integrate technologies and tools into the infrastructure as they are adopted.
